Description
Technical field
The invention belongs to the technical fields that energetic material and explosive manufacture, and in particular to a kind of high intensity titanium-based fiber is fried
Medicine.
Background technology
On mankind's modern historical, explosive has played irreplaceable role at military affairs, civilian aspect.Though however,
Many years have been developed in right explosive, have also made significant headway, but need to improve in terms of some, improve.For example,
How to increase explosive energy in limited bulk to improve Efficiency of Explosive, how to improve the mechanical property of explosive so as to improve explosive
Security during production and transport etc..To improve the energy density of explosive, the method that countries in the world have generally used is
Aluminium powder is added in explosive.The addition of aluminium powder can improve the quick-fried heat of explosive, underwater bubble energy, improve the acting ability of explosive.But
The addition of aluminium powder also brings some harm, and the addition of aluminium powder easily forms hot spot in explosive so that the sensitivity rise of explosive, peace
Full property reduces.And Aluminum Powder Production Process is complicated, and seriously polluted, aluminium powder large specific surface area, surface oxidation is serious, causes energy sharp
With rate than relatively low.And the energy comparison that titanium is discharged through peroxidating is high, as a kind of energetic material, energy can be improved by adding in explosive
Amount, and the density of titanium is 4.54g/cm3, the addition of titanium can significantly improve the volume energy of explosive.And in the mechanics for improving explosive
Performance is leavened dough, and the metal generally added in all cannot make the mechanical property of explosive be improved significantly.Especially in military aspect, explosive
Mechanical property it is poor ammunition can be caused to store, transport, occur in emission process it is early quick-fried, it is by mistake quick-fried, cause life, on property on
Irremediable loss.And titanium and its alloy have the characteristics that high intensity, threadiness, which is made, in titanium and its alloy adds in explosive,
The mechanical property of explosive can be improved, the security of explosive is made to be greatly improved, this is a very huge progress.
The content of the invention
It is an object of the present invention to provide a kind of using titanium and its alloy as the composite explosives of metallic addition, this is fried
The volume energy density of composite explosives and the mechanical property of composite explosives can be remarkably reinforced in medicine, improve the security of explosive.
Technical scheme is as follows：
The high intensity titanium-based fiber explosive of the present invention, composition include titanium fiber or titanium alloy metallic fiber and fry
Medicine, which is characterized in that the high intensity titanium-based fiber explosive is by titanium fiber or titanium alloy metallic fiber and general explosive
Composition.Wherein titanium fiber or titanium alloy metal fiber content are 10% -40%, and general explosive content is 90% -60%,
Binder content is 1% -10%.
Titanium alloy metallic fiber in the titanium alloy fiber explosive, can be titanium magnesium alloy metallic fiber, and titanium aluminium closes
Golden metallic fiber, titanium manganese alloy metallic fiber etc..
Metallic fiber in the titanium-based fiber explosive can be used alone titanium fiber, and also can be used alone one kind
Titanium alloy metallic fiber can also be mixed by titanium alloy metallic fiber not of the same race, titanium fiber and titanium alloy metal can also be used
Fiber is used in mixed way.
The titanium fiber or titanium alloy metallic fiber is a diameter of 8-50 μm of fibrous metal, titanium fiber
Or titanium alloy metal fiber length can change according to made explosive length-flexible, as long as ensureing that length direction is much larger than diameter
Can, such as can be 1-10cm.
The explosive refers to all kinds of explosives of the prior art, can be single chmical compound explosive such as hexogen, and octogen is terraced
Grace ladder waits or composite explosives such as B explosives, nitrolite, emulsion, aqueous gels etc..
The binding agent can be paraffin, and polyamide, polyurethane, silicone is poly- to nitrify glycidol, and poly- nitrine shrinks
Glycerin ether etc..
Compared with existing explosive, high intensity titanium-based fiber explosive of the invention, since the titanium for adding high intensity is fine
Dimension or titanium alloy metallic fiber are compared by experiment and show that the volume energy of explosive is significantly improved.Compared by experiment
It show that titanium fiber or titanium alloy metallic fiber explosive tensile property have compared to the explosive for being not added with metallic addition to change greatly very much
It is kind, it is described further below by embodiment.
Only focus on that energy density is different from conventional explosives, explosive of the invention is while energy density is taken into account in explosive
There is very big progress in terms of mechanical property.The explosive strengths in tension and compression of the invention is that several times of conventional explosives are even tens of
Times.This causes the security performance of explosive to be greatly improved so that explosive can use in more complicated environment.
Application prospect is extensive, and in the production of explosive, storage is used, the raising based on security performance can be significantly in transport
Reduce accident rate.In military field, can effectively avoid since the morning of ammunition strength problem initiation is quick-fried, quick-fried generation by mistake,
Improve fullfledged combat capability.Civil field, under the complex environment more demanding to explosive, which can give full play to its work
With.
